This house is fantastic for visiting Bangkok. Perfect location, nicely decorated. Close to everything in Thonglor, most of it is walking distance. It's close to the onsen which is a must (if you like that kind of thing, Google onsen if you're not sure what that is).
Check in process is very easy and Viia and her team were extremely good in responding.
Beds are a bit hard, and sofa isn't the most comfortable are the only two criticisms I would have, but hopefully they can find some solutions to those things.
All in all it is fantastic value, would definitely stay again.
